The scoring tool 15 is flared. at its end so as to be adapted to press the reinforcing material 3 into the angle of the lip an, as shown by Fig. 2. This tool is carried by a plunger 38 mounted in a guide -member 39. The guide member has a pin-and-slot connection it) with the overhanging bracket 12. A spring 41 contained in the guide member 39 normally depresses the plunger with relation to said member. The spring surrounds theplunger and is compressed between a portion of the guide member and a pin 42 extending through the plunger. The upper end of the guide member is pivotally connected, as indicated at 43, with a lever 41. The fulcrum of the lever is indicated at 45. is connected by a rod 46 with an eccentric strap 47. The strap 47 engages an eccentric 48 which is keyed or otherwise affixed to the driving shaft 2 Vhen the machine is in operation, the guide member 35) is oscillated through a short are about its fulcrum 14-0, thus causing the scor ing tool 15 to vibrate toward and from the feeding disk 14. \V hen the insole is in 013-, erative position, the lip 41; stands between the tool 15 and the feeding disk 14, while the opposite side of the sole is engaged by the support 13. The movement of the tool 15 toward and from the feeding disk presses the reinforeim material into the an le of the a lip. The. disposition and o )eration ofthe guide member 3:9 causes an increase. of spring tension when the tool is moved toward the feeding disk H, and a correspondingdecrease of tension when the tool is moved. away from the feeding disk. In order to keep the work in operative. relation to the feeding disk when the tension of the spring 41 is increased, the spring '18 which raises the work support 13 is preferably stronger than the spring 11 which acts upon the scoring tool. For the purpose of removing and inserting the work, the member 1?) -y be depressed by a treadle suchas that indicated at 49. The margin of the reinforcing material may be left in the position shown by Fig. 2, for the purpose of pressing the material into the angle behind. the 'lip.

The sole may thereafter be subjected to a second operation for pressing the reinforc-v ing material against the outer side of the .hp and into the angle between the hp and forcing material will, in the latter instance pass under the rim of the feeding disk 14.
